Abstract

The invention relates to the technical field of automobile part testing, and particularly relates to a magneto-rheological damper performance testing device. The magneto-rheological damper performance testing device comprises a power unit, a guide mechanism, a force sensor and a displacement sensor, and is characterized in that the power unit is used for enabling a magneto-rheological damper to be tested to move in a reciprocating manner along a guide direction of the guide mechanism; the force sensor is used for detecting information of a damping force generated by the magneto-rheological damper to be tested when the magneto-rheological damper to be tested moves in the reciprocating manner; and the displacement sensor is used for detecting displacement information of the magneto-rheological damper to be tested when the magneto-rheological damper to be tested moves in the reciprocating manner. The performance testing device is diversified in test function, and can meet a test requirement of excitation adjustability of the magneto-rheological damper and test inclusivity for different models of magneto-rheological dampers.

Description

technical field [0001] The invention relates to the technical field of auto parts testing, in particular to a performance testing device for a magneto-rheological shock absorber. Background technique [0002] The magnetorheological shock absorber is a new type of intelligent shock absorber with online adjustable damping force. It utilizes the non-Newtonian rheological properties of magnetorheological fluid under a magnetic field, and can adjust the damping of the shock absorber in real time according to different working conditions to improve the comfort and handling stability of the vehicle. Due to its superior damping adjustment, fast response, good reliability, and low energy consumption, the magneto-rheological shock absorber is used in the field of vibration control and vehicle body roll stability control with the help of semi-active suspension. More and more applications. [0003] In the research and development of vehicle anti-rollover control system using magnetorh...
